How to measure Golang integration test coverage?

Question

I am trying to use go test -cover to measure the test coverage of a service I am building. It is a REST API and I am testing it by spinning it up, making test HTTP

As far as I know, if you want coverage you need to run go test -cover.

However it is easy enough to add a flag which you can pass in which will enable these extra tests, so you can make them part of your test suite but don't run them normally.

So add a command line flag in your whatever_test.go

var integrationTest = flag.Bool("integration-test", false, "Run the integration tests")

Then in each test do something like this

func TestSomething(t *testing.T){
    if !*integrationTest {
        t.Skip("Not running integration test")
    }
    // Do some integration testing
}

Then to run the integration tests

go run -cover -integration-test
